Guest host Stephanie Potter interviews Barbara Ford, Marilee Dea, and Pat Sanders who are going as part of a contingent of "Gray Haired Ladies" to Washington DC to protest the Keystone XL Pipeline, a proposed 1,700 mile pipeline that would carry tar sands oil from Canada to refineries on the Gulf of Mexico. The Keystone Pipeline would be under a lot of pressure -- pumping tar, after all; and subject to breakage. In passing from Alberta to Texas, it would cross through six states and the "largest aquifer in the world." The women hope to join thousands of people from across the continent, including environmentalist Bill McKibben, actor Danny Glover and climatologist James Hansen, in a wave of sustained sit-ins. The protest runs from August 20 to Sept 3, and the Gray Haired Ladies will be participating on August 24. For some of them it will be their first-ever protest: "We are women over 50 from the Columbia Ecovillage, some have never demonstrated before. Peg, a hair stylist from Spokane Wa, Ann, a school secretary, Pam, a retired lawyer and nurse, Barbara, a counselor and facilitator, Marilee, a nurse practitoner and urban farmer." --Marilee (Listen to audio here: http://kboo.fm/node/30364)
